21. In materials science and engineering, the pascal measures the stiffness, tensile strength and compressive strength of materials. 22. Initially, composite restorations in dentistry were very prone to leakage and breakage due to weak compressive strength . 23. This aligns the molecular structure of the fiber in a better configuration for tensile and compressive strength . 24. For ordinary uses, stone having a compressive strength of 5, 000 lb per square inch is satisfactory. 25. In the study of strength of materials, tensile strength, compressive strength , and shear strength can be analyzed independently. 26. Hence calculating the compressive strength of a material from the given equations will not yield an accurate result. 27. By contrast, Panola Mountain has a flakier rock with less compressive strength due to differences in cooling rates. 28. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel. 29. This is quantified as compressive strength , shear strength, tensile strength depending on the direction of the forces involved. 30. Eads argued that the great compressive strength of steel was ideal for use in the upright arch design.
